The horn doesn't operate?

Hello,

There is a relay associated with the horn of this vehicle.
It is located in the junction box under the hood (see diagram).
Visually inspect the relay for any corrosion or bunt pin(s).
You can also test the functionality of the relay.

You also want to make sure that you are getting power to the relay. If the relay is good then check to see if you have power to the connector that plugs into the horn. If you have power then it is a faulty horn.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
